In flue gas filtration applications, such as metallurgy, chemical processing, carbon black production, cement manufacturing, power generation, and waste incineration, some processes operate under continuously high-temperature conditions. Conventional needle-punched felt filter bags often cannot withstand these harsh environments, leading to fiber degradation, loss of mechanical strength, shrinkage, deformation, or premature failure.
Therefore, it is essential to select high-temperature filter bags made from filtration materials with excellent heat resistance and chemical stability, such as aramid, PPS, P84, PTFE, and fiberglass. These advanced filter media maintain reliable mechanical strength and filtration performance under high temperatures, corrosive gases, and demanding dust conditions, effectively extending filter bag service life and ensuring efficient and stable operation of dust collection systems.
